Although Dawner and Princess Sylias are childhood friends and also engaged, she does not remember who he is. Whenever she mentions Dawner to the denizens of the demon castle, she calls him, "D-Whatsit". Due to Dawner being outgoing and friendly to Princess Syalis, he had always disturbed her slumber, thus causing her to have nightmares whenever she dreams about him. He is also known for his poor sense of direction, which explains why Princess Syalis has been captured for four years.
